A novel 3D porous cadmium(II) MOF based on conjugated ligand with potential application for sensing small linear conjugated molecule

A novel 3D porous MOF [Cd-3(ABTA)(2)(DMF) (H2O)(2)] (1) (ABTA=3,4',5-azobenzenetricarboxylate) has been successfully synthesized by solvothermal reaction of Cd(NO3)(2)center dot 4H(2)O with ABTA. Single-crystal X-ray diffraction result reveals that complex 1 possesses a complicated 3D open framework with two intercrossed 1D channels along [200] and [11-1]. The photoluminescence experimental results of the complex in different solvents indicate that complex 1 has potential application in recognizing small linear conjugated molecule.
